. EXTENSION-TABLE.

To all whom t may concern:

Be lit known that I, MARTIN KLUEG, a citizen of the United States of America, residinp' at Sandusky, in the county of Erie and tate of (Ehio, has invented certain new and useful Improvements in Extension- Tfablcs, of which the following is a specification.

My present invention relates to improvements in extension tables of the end extension type and is designed to provide a table of this nature possessing a fixed, integral top, or solid central portion adaptable for use as a center table with a highly polished surface, and extension end leaves by means of which the table may be converted for use as a dining table without disturbing or altering the arrangement and positionof the fixed central portion of the table top.

The invention consists essentially in certain novel combinations and arrangements of parts whereby the duplicate end extensions, which are operable independently of each other, may be moved into proper position in order to increase the capacity of the table as desired, and this attainment may be accomplished without danger of marring thepolished central or fixed top,

or of disturbing it, while at the same time.

the table, when closed and used as a center table, is so constructed and arranged as to present a neat and finished appearance.

In the accompanying drawings I have depicted one complete example and a modified form thereof, showing the physical embodiment of my invention constructed according to the best mode I have so far devised for the practical application of the principles of my invention.

Figure 1 is a top plan view of a table constructed according to my invention, showing an end leaf in extended position.v

Fig. 2 is a side elevation of Fig. 1.

Fig. 3 is a longitudinal, vertical, sectional view of Fig. 1 on line A-A- Fig. 4 is a transverse sectional view of Fig. 1 on line B-B.

Fig. 5 is a transverse sectional view of Fig. 1 on line C--C.

Figs. 6 and 7 are longitudinal sectional views of part of the table showing the positions of parts during two steps in the action of extending the right @11d leaf.

Serial No. 106,595.

Fig. 8 illustrates a modified form of the invention with a plurality of leaves at each end of the table.

Fig. 9 is a detail sectional view to illustrate a swinging strap or yoke employed to give a finished appearance to the table, when not extended.

In vthe preferred vembodiment of my invention as shown in the drawings I utilize a pedestal made up of four posts or legs as- 1, 1, 1, 1, connected by the braces 2, near their lower ends, and the posts are provided with casters 3 as usual. On the tops of the posts the pedestal frame 4 is fixed and comprises a pair of diagonally crossed bars and a rectangular frame. 5 which braces the pedestal and its frame, and serves to hold the parts rigidly connected.

The table top 6 is directly supported from the pedestal frame through the medium of a pair of longitudinally extending spaced bars 7 7 fixed to the pedestal frame and provided with a cross bar 8 fixed to the underside of the table top G and firmly secured to the top surfaces or edges of the two bars 7 7. At the sides of the table, the spaces between the table top and the pedestal frame brace are closed by means of the wooden side bars 8El 8 forming an apron attached to the pedestal frame brace, andmetal angle bars 9 9 fixed to the underside of top and projecting below the upper edge of the side bars. In this manner the spaces at the sides are Closed and the table is given a neat and finished appearance. l

The opposite ends'pof'the table, however are left open to` accommodate the sliding parts or extensible end leaves and their cannections, and there are two extensible leaves operable at opposite ends of the table. The leaves are indicated by the numerals 10 10 and they are each supported on a slide frame or apron as 11 11 which are supported in turn on the bearing blocks 12 12 on the pedestal frame 5.

Diagonal braces 4' at the corners of the table rigidly connect the side bars 8 8fL with theJ stationary part 11il of the apron. Metallic clips 8b at each corner of the table fasten to the side angle bars 9 9 under the top and to the stationary apron 11a, thus holding the top in firm position.

Each slide frame is made up of a pair of spaced metal channel irons connected at their outer ends. by a cross brace and each frame is adapted to be slid in under the top or out from under the top 6, a lug or stop 13 being provided at the under side of the frame to limit the outward movement of said frame, and when the frame is withdrawn, it is supported, like a cantaliver, by bearing up, at its inner end, against the cross bar S beneath the table top. The slide frames or aprons are guided, laterally, by pairs of guide strips 14, 14 secured at the underside of the cross bar 8 and these strips prevent wabbliiig of the guide frames when they are being moved.

Each leaf 10 and 10 is provided with a pair of metallic side plates as 15 15, preferably of angle iron and secured to the undersidepof the leaf, extending longitudinally of the table. Attheir inner ends these plates 'are each lfashioned with an arcuate slot 16, and at their outer ends, each plate is formed with a recess 17 in its lower edge, the slot being used to elevate and depressthe leaf. in connection with a pin 18 projecting 'inwardly from the plate, and the recess being adaptedto seat over a pin 19 at the o'uter end of the channel bars, when the leaf is in elevated position. The leaves are each provided at their under side near the outer edge, with a hand hold or recess 2O by which they are grasped when being pulled out, and the leaves are each provided with a locking catch orihook as 21 adapted to engage in the notch 22 in the under side of the table top 6 near its edge, to hold the leaf against displacement. A pull wire 23 is supported on a cross bar 24 between the side arms of the frame, and by means of this pull wire the hook may be released preparatory to shoving the extension leaf under the table.

To give a neat and finished appearance to the table when the extension leaves are not being used, I provide a pair of swinging metal plates 25 25, slot-ted at their bent ends 26, and hung on pivot pins 27 projecting from the angle irons 9, 9. These plates, when the leaves are not in use, are swung up to a horizontal position, as indicated in Figs. 2 (at the left) and 9, the latter figure showing the plates in section. Before the leaves are pulled out to extended position, these swinging or pivoted plates are first turned to lowered Iposition as in Figs. 2 (at the right) 3, etc. A supporting bracket 2S is provided beneath the pedestal frame upon which the foldable mat 30 may be stored when not required.

In Fig. 8 the frame 31 is elongated to accommodate an additional leaf 32 which is operated in manner similar to the leaf in the other figures, but when both leaves shown in Fig. 8 areused, of course the frame will pull out a greater distance to allow for use of the second leaf.

In operating the extension table, the yoke 25 is firstswung to its vertical position and thenv the leaf is grasped with the hand at its edge and the fingers in the recess 2O which may have a hand plate attached. The leaf is then pulled out to the position of Fig. G, the slidable frame being pulled as far as the stop lug 13 will permit. rThe leaf is now elevated relatively to the slidable frame and as it is lifted it is guided by the arcuate slot 16 so that the recess 17 in plate 15 may seat over the pin 19. The leaf is thus supporter at the lower end of the slot 16 by its pin 1S and by the recess or notch 17 and pin 19, as in Fig. 7. The slidable fi'aine and leaf are now pushed in towai'd the center top 6 and the latch 21 hooks in the notch 22 in the top 6 and is held there as shown in Fig. 3.. It will be noted that the surface of the leaf 10 and the top of the mat 30 are flush, thus providing a smooth even surface, andas the leaf does not usually require a mat for protection, a saving is therefore made both as to expense and time and labor. `When storing the leaf under the table top the above operation is of course reversed.

Vhat I claim is rIhe combination in an extension table with a fixed top portion, a fixedv frame and supporting blocks thereon, of a lframe slidable on the blocks and provided with ,oppositely arranged pairs of pins, a leafhaving opposite end plates each provided with an elevating arcuate slot at the inner end and a supporting recess at the outer end to co-act with said pins for elevating and supporting thefleaf with relation to the slidable frame, whereby the slidable frame, when pulled out acts as a cantaliver fulcrumed on said blocks with its inner end engaging underthe fixed table top portion.

In testimonywhereof I affix my signature.
